I hear it a lot from people that I look like someone they know or like their some relative?

It's thru our DNA genes. It gives us many look alike body doubles around the world. I also it that allot. And I've traveled around allot and I've seen my look alike doubles and many of others like alike doubles. My problem now is I forget who is who. When friends in one state with one with different name then another in another STATE. It get confusing at times. But my belief there is that they like cousin but like 10th to 20th cousin and being from same DNA family genes they look alike. Or close enough alike that until you talk to them or see them together you can not see a differences.
